[0002] A microwave electric vacuum device is usually composed of five parts, i.e., an electron gun, a slow wave structure, an energy transmission structure, a collector, and a magnetic system. The electron gun emits a stable electron stream; the slow wave structure provides a space for interaction between microwaves and an electron beam; the energy transmission structure can efficiently transmit microwave signals; the collector recycles electrons; and the stable magnetic field provided by the magnetic system can effectively constrain the electron stream emitted by the electron gun to make it pass through the slow wave structure according to a specified route, so as to improve the working efficiency of the device. It can be seen that the magnetic system plays a crucial role in the microwave electric vacuum device.

[0003] With the development of the industry, more and more high-strength magnetic fields are applied to microwave electric vacuum devices. The strong magnetic force generated by the magnetic field makes the debugging and installation of the vacuum device more difficult, and is accompanied by certain safety risks. Therefore, how to install the vacuum device at a suitable position of the magnetic system is very important.
